Technical Field
The utility model relates to a general building structure's connection technical field especially relates to a newly-increased enhancement sloping beam connected node under floor.
Background
The beams under the building floor bear bending moment caused by the floor, and normally do not bear pressure or tension along the beam direction. However, in some special cases, if an inclined column is used in the reconstruction of the existing building (for example, the reducing reconstruction of the building), or if the structure of the building itself has strength problems beyond expectation (for example, the load-bearing wall is illegally dismantled in decoration), the existing beam in the building needs to bear extra tension or pressure.
The beam is subjected to bending moment, and is subjected to axial pressure, so that the beam is bent more and is easy to deform in a destabilizing way. If the beam is subjected to a tensile force in the axial direction, the beam is elongated, so that the concrete floor slab above the beam is driven to be elongated, and the tensile capacity of the concrete is extremely poor. Meanwhile, the original beam column node is possibly not suitable for transmitting the pulling force, and the possibility of being damaged by pulling exists. Therefore, in both adverse situations, additional reinforcing oblique beams are required to ensure that the building can still be used normally.
However, if the reinforcing inclined beam is additionally arranged below the floor slab, the reinforcing inclined beam is difficult to be connected with the existing part due to the interference of the floor slab at the top, and meanwhile, the reinforcing inclined beam can apply extra bending moment in the horizontal direction to the original beam.

Detailed Description
As shown in fig. 1-2, a newly added reinforced oblique beam connection node under a floor slab is used for connecting an original beam 1 under the floor slab with a newly added reinforced oblique beam 2, and the reinforced oblique beam 2 is used for reinforcing a current floor when the bearing capacity of the original beam 1 of the current floor is insufficient; the connecting node is a rigid connecting node, and the reinforced oblique beam 2 is arranged between two adjacent and parallel original beams 1 and is fixedly connected with the original beams 1 through connecting brackets 3 arranged on the side surfaces of the original beams 1;
the connecting bracket 3 is arranged instead of directly installing the reinforced oblique beam 2 on the original beam 1 because the top of the beam is provided with a floor slab and constructors need to construct on the back. If the reinforcing oblique beam 2 is directly installed on the original beam 1, positioning, preliminary fixing and connection are simultaneously completed in the state that overhead construction is needed in the installation process, which is very difficult. If the connecting bracket 3 is arranged, the positioning, the primary fixing and the connection can be separately carried out.
The reinforced oblique beams 2 on the same floor enclose a grid-shaped structure, and the plane figures of the grid-shaped structure are vertically symmetrical and horizontally symmetrical, so that the resultant force of the tensile force or the pressure applied by the outside in the whole grid-shaped structure is ensured to be 0. A single grid of the grid-shaped structure is rhombic, the original beam 1 is positioned on the diagonal line of the rhombic grid, and four reinforcing oblique beams 2 at the connecting node positions of the original beam 1 and the reinforcing oblique beams 2 are combined into a structure shaped like a Chinese character 'mi'; thereby ensuring that the reinforcing oblique beam 2 does not apply bending moment in the horizontal direction to the original beam 1.
The upper surface of the reinforced oblique beam 2 is lower than the upper surface of the original beam 1 on the same layer. Thus, there is a gap between the reinforcing stringer 2 and the floor, and the installation is not affected by the proximity of the reinforcing stringer to the floor.
Connect bracket 3 for one end with strengthen 2 butt joints of sloping roof beam and the variable cross section I-steel that other end web widen gradually, connect the web of bracket 3 near the one end of original roof beam 1 and the web welded connection of original roof beam 1, and connect the flange board that bracket 3 is near the one end of original roof beam 1 and pass through connecting plate 4 and the web welded connection of original roof beam 1, the connecting plate 4 of the web both sides of original roof beam 1 uses the web to set up as the plane of symmetry. The connecting structure is designed to satisfy the above-mentioned requirement, and ensure that the connecting surface of the reinforced oblique beam 2 and the original beam 1 is long enough. At the joint of the reinforced oblique beam 2 and the original beam 1, the reinforced oblique beams 2 on two sides of the web plate of the original beam 1 are mutually symmetrical by taking the web plate as a symmetrical surface, so that the reinforced oblique beam 2 can not apply bending moment in the horizontal direction to the web plate.
The part of a flange plate of the connecting bracket 3, which is positioned above the web plate, is a bracket patch plate 31 independently arranged with the web plate, and the bracket patch plate 31 is connected with the web plate of the connecting bracket 3 in a welding way. Here, since there is a floor above the connecting corbels 3, the welding work above the web of the connecting corbels 3 cannot be performed if the corbel supplement plate 31 is not provided.
The connecting bracket 3 is connected with the reinforced oblique beam 2 by bolt-welding. The web plates are connected through steel plates arranged in a riding seam and high-strength bolts penetrating through the steel plates, and the flange plates are connected in a welding mode. This connection is chosen instead of the more simple all-welded connection because the floor is present above the reinforcement stringer 2, so that the welding process of the components is severely limited and the reinforcement stringer 2 cannot be spot welded in place. Therefore, the high-strength bolts are used for fixing and then welding is carried out.
In this embodiment, the building in which the original beam 1 is located is a steel structure frame-core tube structure system, the original beam 1 is arranged between a center tube and a ring beam of the building and perpendicular to an outer wall of the building adjacent to the end of the original beam 1, and the edges of the grid-shaped structure surrounded by the reinforced oblique beams 2 are respectively and fixedly connected with the center tube and the ring beam.
The utility model discloses the installation order of well each part is as follows:
installing a connecting plate 4 → welding the connecting bracket 3 with the connecting plate 4 → installing and welding the bracket patch 31 → positioning the reinforced oblique beam 2 → connecting the reinforced oblique beam 2 with the connecting bracket 3 through a high-strength bolt → welding the flange plate of the reinforced oblique beam 2 with the connecting bracket 3.
The above-mentioned embodiments are merely illustrative of the preferred embodiments of the present invention, and are not intended to limit the scope of the present invention, and various modifications and improvements made by those skilled in the art without departing from the spirit of the present invention should fall within the protection scope defined by the claims of the present invention.
